Study Notes

Heart Anatomy and Auscultation Points

  • 2nd left intercostal space: Location of the pulmonic valve area.
  • 3rd left intercostal space: Known as Erb's point, a key auscultation site.
  • 4th left intercostal space: Corresponds to the tricuspid valve's position.
  • 5th intercostal space, midclavicular line: Site for placing a stethoscope when taking an apical pulse.
  • 2nd right intercostal space: Location for the aortic valve area.

Heart Sounds

  • S1 (First heart sound): Marks the beginning of systole, generated by the closure of mitral and tricuspid valves, best heard in the mitral area.
  • S2 (Second heart sound): Indicates the end of systole, produced by the closure of aortic and pulmonic valves.
  • S1 and S2: Referred to as "lub dub," representing the two primary heart sounds.

Apical Pulse

  • Apical pulse: Obtained near the apex of the heart on the left side, below the nipple, using a stethoscope.

Specific Locations for Heart Sounds

  • Aortic (S2): Found at the right 2nd intercostal space.
  • Pulmonic (S2): Located at the left 2nd intercostal space.
  • Erb's point: Identified at the left 3rd intercostal space.
  • Tricuspid area: Present at the lower left sternal border, specifically the 4th intercostal space.
  • Mitral (S1 or Apical pulse): Situated at the left 5th intercostal space, midclavicular line.
